Application filed September 7, 1915. Serial No. 49,165.

To all w hom it may concern:

Be it known that I, WILLIAM MILLER, a citizen of the United States,residing at Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain new and useful Improvements in Ships, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention pertains to improvements in sea vessels.

An object is to provide a vessel a portion of which will remain free, ornearly so, from rocking movement and thereby enable passengers to ridetherein without sea sickness and without the other inconveniencesencountered in a rocking vessel.

Another object is to provide safety for passengers in the event ofsinking of the vessel.

A further object is to utilize the rocking movement of the vessel forstoring power or for accomplishing other work, such, for example, aspumping water from a leaky vessel.

Other objects and advantages of the invention will be set forth in theensuing description.

The accompanying drawings show one embodiment of the invention inpractical form.

Figure 1 is a plan view of the improved vessel. Fig. 2 is a sideelevation, with a portion broken out to expose interior construction.Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 1.Fig.

41 is a similar view taken on the line H of Fig. 1, but showing theouter hull of the vessel listed to one side.

Like characters of reference designate like parts in all the figures.

The improved vessel includes an outer hull 5, not materially differentfrom that of the ordinary vessel.

In carrying out the objects stated, an inner and smaller hull 6, capableof carrying the passengers and creW in an emergency, is mounted withinthe outer hull 5; this inner. hull being pivoted to the outer hull on afore-and-aft axis line. In pivoting the inner hull 6, a pivot-shaft 7 isset rigidly on its rear end, and a similar pivot-shaft 7 on its frontend; these pivot-shafts being set rigidly in bearings 8 onthe upper deck9 of said hull 6. Each pivot-shaft 7 rests revolubly in a bearing 10which is mounted on the deck 9 of the outer hull 5, and bearings 11 areprovided on said deck at the ends of said pivot-shafts to prevent undueend thrust. The bearings 10 are left open for the release of thepivot-shafts 7 and the inner hull 6 in case of sinking of the outer hull5, and these pivot-shafts are held down in said bearings by rope orother suitable flexible material 12 which may be easily severed whenrequired, the ends of this rope being extended down through the deck 9and fastened in any suitable manner, as at 13.

With the hulls 5 and 6 arranged in this way, the inner one 6 is almostentirely free from rocking influence of the outer one.

In further arrangement, means for storing energy are provided. Inproviding this means a pump 14 may be mounted in the outer hull 5 on asuitable base 15, and the piston-rod 16 of this pump connected to acrank-pin 17 on the hull 6 by a connectingrod 18. A similar pump 19 maybe mounted on the base 15 and have its piston-rod 20 connected to acrank-pin 21 on the hull 6 by a connecting-rod 22. One of these pumps 14and 19 may be employed to pump out water that may leak into the hull 5,and the other connected to a storage tank 23 by a pipe 24 to storecompressed air for any desired purpose. It will be seen that the rockingmovement of the outer hull 5 with respect to the inner hull 6 willoperate the pumps 14 and 19; and it will be further seen that by merelyanchoring the outer hull 5 where the waves may rock it the vessel may beconverted into a temporary power plant.
